Transaction FAGLPLC Planning newGL column issue

Hello,

when defining a planning layout within FAGLPLC I can define (e.g.) two columns for January and February.

The system opens them for input also (o.k.).

However, as soon as I enter a third column (e.g. for March) this and subsequent columns are not open

for entry during planning.

Is there a limitation concerning the number of colums during planning within NewG?

Thanks a lot for input

Thomas
